The same construction is provided for the left-hand portion of the platform, see FIG. 4.

The mop head 55 further includes a force transmitting member 120, the force transmitting member being movable into and out of engagement with the platform 60. The force transmitting member 120 includes a substantially flat platform 121 having a top surface 122, a bottom surface 123 and a peripheral end surface 125 interconnecting the top and bottom surfaces. An upstanding side wall 127 extends around the platform 121 in the shape of a rectangle and is spaced from the peripheral surface 125 to form a border 124 between the side wall 127 and the peripheral surface 125. The side wall 127 is provided with an outer peripheral abutment surface 128. The force transmitting member 120 is provided with two spaced apart upstanding ears 130, each of the ears 130 having an aperture 131 therein, the apertures being in registry. The force transmitting member 120 includes four diagonally positioned struts 123 extending from the respective corners formed by the side wall 127 inwardly toward the upstanding ears 130. A pair of parallel and spaced apart reinforcement members 134 are provided between the upstanding ears 130. The struts 133 and 134 serve to distribute force more evenly over the entire surface area of the platform 121, as will be explained.

The force transmitting member 120 is shaped to fit within the platform 60 so that the upstanding ears 130 pass through the spaced apart slots 69 and abut the inner surfaces of the spaced apart trunnions 66 so that the apertures 131 are in registry with the apertures 67. Further, the abutment surfaces 128 of the side walls 127 abut the abutment surface 101 of the supports 100 which also abut the ledge 124 formed between the side wall 127 and the peripheral surface 124 of the force transmitting member to provide for frictional holding forces to maintain the force transmitting member 120 in engagement with the platform 60. Generally, the abutment surface 76 of the reinforcement member 75 is spaced from the reinforcement member 134 due to the maintenance of the apertures 67 and 131 in registry. The force transmitting member 120 will snap from a position of engagement with the platform 60, as seen in FIG. 4, to the position shown in FIG. 5, wherein the force transmitting member is spaced away from the platform 60.

There is further provided a dust cloth 140, the dust cloth being generally oval in shape and having a back surface 141 and a dusting surface 142. The dust cloth 140 is softand pliable and is provided with a substantial nap on the dusting surface 142 thereof. The back surface 141 does not necessarily have the na provided on the dusting surface 142.

The dust cloth 140 is larger in surface area than the platform 60 so that a marginal portion of the dust cloth 140 is provided after the dust cloth has been mounted to the mop head 55. The marginal portion of the dust cloth 140 extends outwardly of the platform 60 to facilitate the removal of the dust cloth from the platform, as will hereinafter be explained.

There is also provided a separable fastening device 150 including a first fastening member 155 having a substantially rigid rectangular backing sheet 156 having a peripheral abutment surface 157, the rigid backing sheet 156 carrying a plurality of closely spaced interengageable first hooking elements 158 extending therefrom. As seen, two first fastening members 155 are provided for each side of the platform 60 for a total of four fastening members 155, each of the fastening members 155 snapping into position within the clasping members as shown in FIG. 4 and being removable from the platform 60 as shown in FIG. 6.

The separable fastening device 150 further includes a second fastening member 165 which includes an elongated backing sheet 166 having a plurality of closely spaced interengageable second hooking elements 168 extending upwardly therefrom, the second fastening member 165 being fixedly mounted on the back surface 141 of the dust cloth 140 by the stitches 169. It is apparent that there are two second'backing members 165, the backing members 165 being spaced apart and parallel and having their longitudinal dimension extending transversely of the dust cloth 140. The distance between the second fastening members 165 generally corresponds to the distance between the fastening members 155 when they are snapped in place in the clasping device consisting of the resilient fingers 85, 91, 93 and 103. It will be noticed that the surface area of one of the fastening members 165 is substantially less than the surface area of side by side fastening members 155 to provide for easier mounting of the dust cloth 140 on the platform 60. i

There is also provided for the mop head 55 a mop handle 175, the mop handle 175 including an elongated pole or rod 176 terminating in a crosspiece 177, the crosspiece 177 being journaled for rotation in the aligned apertures 67 and 131 provided in the trunnions 66 and the upstanding ears 130. A yoke-shaped member 180 is positioned with the crosspiece 177 and provides two stub axles which fit into the respective ones of the apertures 67 and 131, the yoke-shaped member l80-being resilient so as to enable the member 180 to be compressed to permit removal of the stub axles from the apertures 67 and 131 and the mop handle 175 from the mop head 55.

The operation of the combination dust cloth and dust mop 50 will 'now be set forth. The dust cloth 140 may be used alone as a dust cloth or in combination with the mop head 55 to provide a dust' mop construction 50. When the dust cloth 90 is detached, it may be used to dust furniture and the like as any other dust mop, the shag or nap depending from the dusting surface 142 thereof providing a good dusting surface. When it is desired to convert the dust cloth 140 into a dust mop construction 50, the dust cloth 140 is positioned on a support surface such as the floor with the shag or nap side, that is the dusting surface 142, positioned downwardly .and the second fastening members 165 fixedly adhered to the back surface 141 of the dust cloth 140 positioned upwardly. The mop head 55 in its fullyconstructed condition, as hereinafter will be explained, is positioned over the dust cloth 140 so that the first fastening members 155 are in registry with the second fastening members 165. The mop head 55 is then firmly pressed on to the cloth 140 thereby to mount the cloth 140 to the mop head 55 with the engaged fastening members 155 and 165 providing spaced apart fastening devices.

The greater surface area of the fastening members 155 compared to the fastening members 165 permit the mounting of the dust cloth 140 to the mop head 55 without precise alignment of the fastening members 155 and 165. The combination of the dust cloth 140, the mop head 55 and the mop handle 175 provides the dust mop and dust cloth construction 50.

The fastening members 155 and 165 each are provided with a plurality of closely spaced interengageable hooking elements such as those described in U. S. Pat. No. 3,099,235, issued to G. deMestral, Nov. 21, 1961 (the disclosure of which is incorporated herein by reference), and sold under the trademark VELCRO.

The first fastening members 155 may be snapped'into and out of position in the mop head 55 between the positions shown in FIG. 4 (the left-hand portion thereof) and the position shown in FIG. 2. The advantage of the easy removability of the first fastening members 155 is' that they may be replaced if they become damaged or wear out without replacing'the entire mop head 55. Since the fingers 85, 91, 93 and 103 are resilient, the first fastening members 155 can be snapped into and out of position on the mop head 55, the bosses 110 and 1 l 1 preventing the fastening members 155 from sliding transversely of the mop head 55 when the fastening members 155 are in the snapped-in position thereof. Removal of the fastening members'155 from the mop head 55 is facilitated by the openings 82 in the peripheral wall of the mop head 55. A 'screw driver or other flat instrument may be inserted into the openings 82 and the fastening members 155 may thereafter be pried from the resilient fingers holding them in position.

The force transmitting member 120 is also removable from the platform 60 of the mop head 55, the force transmitting member 120 snugly fitting between the supports so that the abutment surface 128 of the force transmitting member is in contact with the abutment surface 101 of the support 100, thereby firmlyand frictionally to hold the force transmitting member 120 within the platform 60. Further, the upstanding ears 130 frictionally engage the inside of the trunnions 66, thereby to provide additional frictional engagement between the platform 60 and the force transmitting member 120. Since the ends of the yokeshaped member 180 fit into and through the apertures 131 in the upstanding ears 130, force applied to the handle 175 is transmitted through the upstanding ears 130 along the struts 133 and 134 to the platform 1.21 which platform 121 has a substantial surface area as shown in FIG. 3. The portion of the dust cloth underneath the entire bottom surface 123 of the force transmitting member 120, therefore, will have a uniform of force transmitted thereto and evenly distributed thereover to improve the dusting capabilities of the combination dust cloth and dust mop 50.

It should be noticed that the distance between the backing sheet 156 of the fastening member and the back surface 141 of the dust cloth 140 when the fastening members 155 and are engaged is substantially equal to the distance between the notches 86, 92, 94 and 104 and the bottom surface 123 of the force transmitting member 120. This construction is provided so that a smooth dusting surface is produced when the dust cloth 140 is mounted to the mop head 55, and the entire area of the dust cloth 140 under the force transmitting member 120 contacts the area to be dusted without variations in the force applied thereto.

In a constructional example, the platform 60 may be 12 inches in length, 4 2 2 inches in width and may have a thickness at the end thereof of /16 inch and a thickness at the trunnions 66 of inch. The slots 69 may be three-fourths of an inch long and five-thirty seconds of an inch wide. The distance between the fingers 85 and 91 may be 0.968 inches which is also the distance between the fingers 93 and 103. The force transmitting member may have a length of 7.65 inches and a width of 4.5 inches, the upstanding ears 130 being 1 H16 inch from the center of the aperture 131 to the bottom surface 123 of the force transmitting member 120. The mop head 55 is preferably made from a synthetic organic resin which is scratch resistant and non-brittle.

Polypropylene is the preferred material.
